Etymology: Cephalopholis: Greek, kephale = head + Greek, pholis = scale (Ref. 45335).
Eponymy: This is a toponym referring to the River Niger; the river (or its mouth, in the case of marine species) being the type locality. (Ref. 128868), visit book page.

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 30.5 cm TL male/unsexed; (Ref. 57293); common length : 20.0 cm TL male/unsexed; (Ref. 26999)
Dorsal spines (total): 9; Dorsal soft rays (total): 14 - 15; Anal spines: 3; Anal soft rays: 8. Diagnosis: depth of body 2.8-3.0 in SL; head length 2.5-2.6 in SL; eye diameter greater than interorbital width, eye diameter 4.6-5.5 in HL; flat interorbital area; rounded preopercle, finely serrate, lower edge fleshy; subopercle and interopercle smooth; convex upper edge of operculum; maxilla scaly, reaching well past eye; lateral-body scales ctenoid, without auxiliary scales (Ref. 89707).
Occurs on mud (Ref. 5222), sand, and rock bottoms (Ref. 5222, 57293) in coastal waters, usually above 50 m depth (Ref. 57293). Exceptionally enters brackish lagoons and estuaries (Ref. 57293).

Estimates based on models
Preferred temperature (Ref.
123201): 19.2 - 27.9, mean 25.8 °C (based on 80 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00587 - 0.02699), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
